Dale Earnhardt Jr. ended his NASCAR Cup Series career without a win at one of motorsports' most iconic tracks.

On Lap 75 of Sunday's Brickyard 400, Earnhardt was involved in a log-jam after a restart late in Stage 2 and was forced into the rear of Trevor Bayne's car. The collision knocked Junior's radiator out of place, causing his car to leak fluid over the 2.5-mile Indianapolis Motor Speedway track.

“There were just a bunch of cars slowing down and stopping and caused a chain reaction,” Earnhardt told NBC Sports. “I got into the back of the 6 car (Bayne), they were all getting into each other, and just knocked the radiator out of it.

“We had a great car, I was having a lot of fun, the car was fast, we had a top-10 car for sure. It’s frustrating because I really enjoyed being out there.”
